Don’t run commands that binaries not directly maintained by OPNsense tell you to run on a root shell. Use the builtin CLI commands or GUI to restart squid web proxy.

In fact don’t run root shell commands without consulting the forum or official docs. We are happy to answer questions but can’t guarantee what you are trying to do will do what you expect by a random line of commands. Also check the date stamps in posts on the forum, older commands may stop working or do different things on subsequent major releases.
